The pedometer requires that you walk at least 7 seconds before adding your step count to your daily total.
We incorporated this feature to prevent it from recording simple body movement as a step, such as standing up, sitting down or shifting your weight from one foot to the other while standing. If the pedometer detects 7 seconds of walking movement, it will then start recording on the 8th second (and include the steps you took during the first 7 seconds).
If the pedometer does not detect 7 seconds of walking movement, none of the steps will be counted during that time.
